Protecting the world’s oceans using free and open source geospatial data and tools
summary
Only 8% of the ocean is protected and the goal is 30% by 2030 so geospatial prioritization identifies where to expand protection using species and habitat layers, fishing cost surfaces, and seamount proxies for biodiversity. The workflow uses R packages like prioritizr and oceandatr plus custom packages (spatial gridder, spatial planner, shiny planner) to grid tens of thousands of cells, run over 100 scenarios, and produce maps that closely match Bermuda’s draft MPA proposal.
